WALDEMAR L. VON DE MARWITZ, OF LOS ANGELES, CALIFORNIA.

DOOR-HINGE.

To all whom it may concern:

Be it known that I, WALDEMAR LEOPOLD voN DE MARWITZ, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Door-Hinges, of which the following is a specification.

This invention relates to hinges for doors and has for its object to provide a hinge of simple and improved construction whereby displacement caused by swelling or shrinking of a door orjamb may be corrected and compensated for, thus restoring doors from sagging or otherwise distorted position to a normal position without cutting or patching either the door or door frame or casing and without necessitating the insertion of filling strips or the like.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in an improved hinge, one of the leaves of which is provided with a filling plate adjustably connected therewith and adapted to be interposed between said leaf jamb of the door, thus enabling sagging or displacement of the door to be readily corrected.

The invention further consists in the improved construction and novel arrangement of parts which willhereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings z-Figure 1 is a perspective view of a hinge constructed in accordance with the invention. Fig. 2 is a horizontal sectional view showing the hinge applied to a door and a jamb or casing.

Corresponding parts in both figures are denoted by like characters of reference.

The improved hinge is composed of the which are connected in the usual manner by means of the rod or pintle C. One of the leaves, preferably the one which in practice is attached to or connected with the door jamb or casing, and which in the example illustrated in the drawing is Specication of Letters Patent.

designated by B, is provided with lugs or bosses 1-1 having recesses-2 for the reception of the heads 3 of screws 4 which are threaded through apertures formed in the said hinge leaf B. The terminal ends of the screws 4 are reduced and extended through apertures 5 in a filling plate 6 which is of a size approximately corres onding to that of the hinge leaf B with which the said filling plate is connected by the screws; the re duced ends of the latter being upset, as shown at 7 within the apertures, which. latter are countersunk for the reception of the upset portions of the screws which latter are thus swiveled in the filling plate 6. Thus it will be seen by proper adjustment of the screws in the threaded apertures of the hinge leaf B, the filling plate 6 may be moved to or from the said hinge leaf, and held securely at various adjustments. The hinge leaf A is provided in the face thereof with recesses 8 sufficiently large to accommodate the bosses or projections 1-1 when the hinge leaves are folded together, in the act of closing the door to which the hingeis applied. The operation and advantages of this invention will be readily understood from the foregoing description taken in connection with the drawing hereto annexed. The door, a portion of which is shown at 9 is connected with the jamb or casing l0 in the usual manner by a plurality of hinges, two hinges being usually employed. In the event of displacement or dislocation of the door, caused by swelling or shrinkage of the door or jamb, the parts may be readily restored to proper posi` tion by adjustment of the hinge leaves 'B with relation to the adjustable filling plate 6 which latter, as will be readily understood, are fitted in contact with the door jamb or casing; it being obviously necessary first to loosen the usual screws whereby the hinge is mounted in position, and for the passage of which the customary countersunk apertures 11 are provided.

It very frequently happens, after doors have been hung, occurs whereby the doors are caused to sag or otherwise be placed at registry with the casings. When hinges of ordinary construction are used it is a matter of some difficulty.

that swelling or shrinkage to restore :the doors to normal position; anA

hinges of the improved construction herein with openings for described are used, it is only necessary to loosen the screw or screws, after which, by adjusting the screws 1l,.the hinges maybe adjusted to compensate for any displacement of the door, thus restoring the latter to registry with the frame or casing without necese sity of cutting orA disguring any portion of the door or casing.

Having thus described the invention, what I claim, is

1. A door hinge, one leaf of which is provided with openings for passage of the usual fastening screws, adjustingI screws threaded through said leaf, and a filling plate provided passage of the fastening screws and having swiveled connection with said adjusting screws.

2'. A door hinge having a leaf provided with recessed lugs or bosses, and threaded apertures in registry therewith, in combination with adjusting screws extending through the threaded apertures and having reduced ends, and a filling plate having apertures engaging the reduced ends of the adjusting screws and connected therewith by upsetting said reduced ends.

3. In a door hinge, a leaf having openings for the passage of the usual fastening screws and provided with sockets or recesses, and a mating leaf having openings for passage of such screws and formed with lugs or bosses adapted `for engagement-with said sockets or recesses, in combination with adjusting screws extending through the lugs or bosses, and a filling' plate carried by and having swiveled connection with said adjusting screws.

In testimony whereof, I aiiiX my signature in presence of two witnesses.
